Question

What is the probability that a cross between a heterozygous dominant yellow-seeded pea plant and a green-

seeded pea plant will produce green-seeded offspring?


1:1

1:2

1:4

1:8

Answer 1

So, using S as yellow and s as green alleles, with a punnett square, we see that two of the four offspring would be green seeds. So, 2:2 is equal to 1:1, so that would be your answer. I included the punnett square I drew for extra help. Good luck!
